GUIDE FOR ATTACHMENT TO A ROOF BOLTER TO ALLOW FOR CORE DRILLING AND METHOD OF CORING

摘要

The present disclosure provides a coring guide (50) for converting a mine roof bolter into apparatus suitable for guiding a coring rod, or drill, into a mine roof, as well as a method for obtaining a geological core from the mine roof using the guide. The guide includes a pair of jaws (52, 54), wherein each jaw has an adapter (52a, 54a) end and a pivotable end. The adapter end of each jaw includes a cavity (72a, 72b) that faces a cavity included in the adapter end of the other jaw, such that the closed jaws form at least a major portion of a cylindrical coring cavity that accommodates a coring rod (100).
